Embodiment Construction

[0064] In order to provide an implementation solution for adaptively adjusting the scanning state according to changes in the heart rate of the scanning object, an embodiment of the present invention provides a scanning method and a scanning device. The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention. And in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0065] CT equipment is a commonly used medical imaging equipment. CT equipment irradiates X-rays to the inspected part and receives the X-rays that pass through the inspected part. Because different organs or tissues absorb X-rays differently, the X-rays transmitted through the receiving...

Abstract

The invention discloses a scanning method and a scanning device. The scanning method comprises the steps that a scanning state of CT equipment is monitored; when a high milliampere radioactive ray scanning state of the CT equipment is switched into a low milliampere radioactive ray scanning state, the scanning duration of the CT equipment under the low milliampere radioactive ray scanning state istimed to obtain the first duration; when the first duration reaches the preset maximum duration, the scanning state of the CT equipment is triggered to be switched from the low milliampere radioactive ray scanning state into the high milliampere radioactive ray scanning state, wherein the preset maximum duration is the longest time which can be sustained by low milliampere radioactive ray scanning on the premise of ensuring that a CT image can be reconstructed. By controlling the continuous scanning time in the low milliampere radioactive ray scanning state, the switching of the scanning state of the CT equipment is controlled, namely the low milliampere radioactive ray scanning state is switched into the high milliampere radioactive ray scanning state to ensure that the CT image can be reconstructed, and the effectiveness of dose adjustment of CT scanning of the CT equipment is improved.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a scanning method and a scanning device. Background technique [0002] At present, the number of detectors on the scanning frame in CT (Computed Tomography, electronic computer tomography) equipment is increasing continuously, the scanning speed is continuously accelerating, and the quality of CT images obtained by scanning is continuously improving, which can realize scanning with a smaller pitch Small organs in the human body, such as coronary angiography using CT equipment to scan the heart, etc. When the CT equipment scans with a small pitch, the scanning gantry rotates one circle, and the distance that the CT bed moves in the direction of the longitudinal axis is relatively short. increasing. [0003] When CT scanning is performed on the heart with a small pitch, according to the heart rate of the scanned object, within a heartbeat cycle, a time period is designated for h...
